Description
Technical field
The present invention relates to a kind of plate drawing system for being used to fix auxiliary operating mode, belong to crane technical field.
Background technology
With the quickening of Urbanization in China, economic fast development, the scale of state fundamental construction is increasing, needs
The weight and lifting altitude for the article to be lifted are increasing, and crawler crane increasingly shows its superiority, and crawler type rises
Heavy-duty machine has obtained swift and violent development.It is secondary to be commonly designed installation in order to improve its lifting altitude and work range for crawler crane
Arm operating mode.
After crane arm support typically assembles on ground, by itself luffing ability by arm support cantilever lifting to operating angle.
Horizontal cantilever lifting state, arm support is one long thin press-bending structure, due to the deadweight of arm support, the whole arm support of arm support especially center section
Downward amount of deflection can be produced, initial deformation will be further increased under arm support axial separation effect caused by luffing power, and cause two
Secondary deformation, so as to increase the structural stress of arm support.Further, arm support length is longer, and arm support weight is heavier, and arm support will have unstability
Danger；To improve the cantilever lifting ability of long-armed operating mode boom system, arm support cantilever lifting security is improved, it usually needs increase waist rope dress
Put, as shown in Figure 1.
Prior art still suffers from following shortcoming：
1. angle is smaller between arm-tie and auxiliary support after auxiliary, auxiliary support axial force is larger, otherwise auxiliary support is from high material
The material of matter, otherwise more complicated, heavier-weight that structure is done, cost are larger；
2. after auxiliary near arm-tie and principal arm hinge area（Such as a-quadrant in Fig. 2）, there is stress concentration phenomenon, it is necessary to which special add
Strength is managed, and can increase the arm support weight of principal arm system；
3. during cantilever lifting, angle is smaller between principal arm arm-tie and principal arm system, arm support length more long angle therebetween is smaller, and angle is got over
Small, caused arm support axial force is bigger.Arm support can produce a downward amount of deflection during cantilever lifting, because the effect of waist rope can make master
Angle between arm arm-tie and principal arm becomes smaller（As shown in figure 3, Fig. 3 of comparison diagram 2）, the increasing of arm support axial force, cantilever lifting safety
Property reduce；
4. arm-tie dumpling is selected after auxiliary is required for individually welding, processing, production cost height with waist rope dumpling point diverse location, each dumpling point；
5. tilting moment caused by the weight of boom system itself is bigger is bigger, the amount of deflection of caused arm support is also got over during cantilever lifting
Greatly, caused waist rope power is also bigger, and complete machine cantilever lifting difficulty is bigger, and cantilever lifting security is lower.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of simple in construction, arm support weight can be reduced, improve arm support by
Power situation, improve the plate drawing system that principal arm opens arm ability and security.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
It is a kind of to be used to fixing the plate drawing system of auxiliary operating mode, including after principal arm arm-tie, waist rope, auxiliary before arm-tie, auxiliary arm-tie with
And auxiliary support, described principal arm arm-tie one end are connected with the junction of principal arm and auxiliary, before the auxiliary arm-tie both ends respectively with
Auxiliary support and the auxiliary connection, the waist rope both ends are connected with the principal arm and the principal arm arm-tie respectively, described
Arm-tie one end and the auxiliary support free end, the other end are connected with the principal arm arm-tie after auxiliary, and arm-tie exists after the auxiliary
Tie point of the tie point with the waist rope on the principal arm arm-tie overlaps on the principal arm arm-tie.
The waist rope is arranged on the principal arm deflection of arm support maximum.
The waist rope is hinged with the principal arm arm-tie, and hinge is drawn the waist rope with the principal arm altogether with arm-tie after the auxiliary
Plate is hinged.
Arm-tie includes 2 groups after the waist rope, the principal arm arm-tie and the auxiliary, is symmetrically distributed in the two of the principal arm
On the mainmast of side.
Connector after 2 auxiliarys between arm-tie and the auxiliary support by isosceles triangle connects.
Arm-tie uses steel plate after the principal arm arm-tie and the auxiliary, and the waist rope uses steel cable.
The beneficial effect that the present invention is reached：
1. relative to prior art, angle increases between arm-tie and auxiliary support after auxiliary of the invention, auxiliary support axial direction
Power accordingly reduces, and contributes to the light-weight design of auxiliary support, and auxiliary weight support frame mitigates, and cost reduces, and cantilever lifting security increases
Add, elevating capacity gets a promotion；
2. arm-tie is articulated with principal arm arm-tie after auxiliary, relative to prior art, after can reducing auxiliary in principal arm system
Arm-tie dumpling point, it is possible to reduce corresponding manufacturing procedure, reduce production cost；Simultaneously in the absence of in prior art（In Fig. 2
A-quadrant）The phenomenon of stress concentration, boom system structure is correspondingly simple, and can reduce the weight of principal arm arm support, cantilever lifting security
Increase, elevating capacity get a promotion；
3. arm-tie is articulated with principal arm arm-tie after auxiliary, auxiliary arm-tie has a point being lifted up relative to principal arm arm-tie
Power,（Such as Fig. 5, shown in Fig. 6, Fs1/Fs2 is principal arm arm-tie power；Fh is arm-tie power after auxiliary, and Fh1/Fh2 is arm-tie power after auxiliary
Component in all directions；Fy is waist rope power）Can avoid in prior art due to the effect of waist rope make principal arm arm-tie with
The phenomenon that angle diminishes between principal arm, and can increase angle between principal arm arm-tie and principal arm, reduce arm support axial force, cantilever lifting
Security increase；
4. angle reduces between arm-tie and auxiliary support after auxiliary, arm-tie stress is corresponding more after auxiliary during arm-tie stress before equal auxiliary
It is small,（Such as Fig. 7, shown in Fig. 8, Fb is auxiliary support axial force；Fh is arm-tie power after auxiliary, and Fh3/Fs4 is arm-tie power edge after auxiliary
The component of all directions；Fq is arm-tie power before auxiliary, the component of arm-tie power in all directions before Fq1/ Fq2 auxiliarys）Contribute to pair
The light-weight design of arm-tie, reduces cost after arm；
5. the weight of boom system and arm-tie itself is significantly reduced, caused tilting moment reduces, cantilever lifting when institute
The amount of deflection of arm support is caused also to reduce, complete machine cantilever lifting difficulty reduces, the increase of cantilever lifting security.
